Features  
Description  
• Overriding RESET Terminates Output Pulse  
• Triggering from the Leading or Trailing Edge  
• Q and Q Buffered Outputs  
The CD74HC221, and CH74HCT221 are dual monostable  
multivibrators with reset. An external resistor (R ) and an

for the circuit. Adjustment of R and C provides a wide

range of output pulse widths from the Q and Q terminals.  
Pulse triggering on the B input occurs at a particular voltage  
level and is not related to the rise and fall time of the trigger  
pulse.  
• Separate Resets  
• Wide Range of Output-Pulse Widths  
• Schmitt Trigger on B Inputs  
• Fanout (Over Temperature Range)  
Once triggered, the outputs are independent of further trigger  
inputs on A and B. The output pulse can be terminated by a
